“Oh, it is maddeningly simple. For here we are with our plots and our schemes, thinking that we are keeping our secrecy – when all the time we are in the very heart and core of our enemy’s stronghold. It’s humorous.”
Anthor did not remove the skepticism from his face, “You honestly believe this theory, Dr. Darell?”
“I honestly believe it.”
“Then any of our neighbors, any man we pass in the street might be a Second Foundation superman, with his mind watching yours and feeling the pulse of its thoughts.”
“Exactly.”
“And we have been permitted to proceed all this time, without molestation?”
“Without molestation? Who told you we were not molested? You, yourself, showed that Munn has been tampered with. What makes you think that we sent him to Kalgan in the first place entirely of our own volition – or that Arcadia overheard us and followed him on her own volition? Hah! We have been molested without pause, probably. And after all, why should they do more than they have? It is far more to their benefit to mislead us, than merely to stop us.”
Anthor buried himself in meditation and emerged therefrom with a dissatisfied expression. “Well, then, I don’t like it. Your Mental Static isn’t worth a thought. We can’t stay in the house forever and as soon as we leave, we’re lost, with what we now think we know. Unless you can build a little machine for every inhabitant in the Galaxy.”
“Yes, but we’re not quite helpless, Anthor. These men of the Second Foundation have a special sense which we lack. It is their strength and also their weakness. For instance, is there any weapon of attack that will be effective against a normal, sighted man which is useless against a blind man?”
“Sure,” said Munn, promptly. “A light in the eyes.”
“Exactly,” said Darell. “A good, strong blinding light.”
“Well, what of it?” asked Turbor.
“But the analogy is clear. I have a Mind Static device. It sets up an artificial electromagnetic pattern, which to the mind of a man of the Second Foundation would be like a beam of light to us. But the Mind Static device is kaleidoscopic. It shifts quickly and continuously, faster than the receiving mind can follow. All right then, consider it a flickering light; the kind that would give you a headache, if continued long enough. Now intensify that light or that electromagnetic field until it is blinding – and it will become a pain, an unendurable pain. But only to those with the proper sense; not to the unsensed.”
“Really?” said Anthor, with the beginnings of enthusiasm. “Have you tried this?”
“On whom? Of course, I haven’t tried it. But it will work.”
“Well, where do you have the controls for the Field that surrounds the house? Id like to see this thing.”
“Here.” Darell reached into his jacket pocket. It was a small thing, scarcely bulging his pocket. He tossed the black, knob-studded cylinder to the other.
Anthor inspected it carefully and shrugged his shoulders. “It doesn’t make me any smarter to look at it. Look Darell, what mustn’t I touch? I don’t want to turn off the house defense by accident, you know.”
“You won’t,” said Darell, indifferently. “That control is locked in place.” He flicked at a toggle switch that didn’t move.
“And what’s this knob?”
“That one varies rate of shift of pattern. Here – this one varies the intensity. It’s that which I’ve been referring to.”
“May I–” asked Anthor, with his finger on the intensity knob. The others were crowding close.
“Why not?” shrugged DarelI. “It won’t affect us.”
Slowly, almost wincingly, Anthor turned the knob, first in one direction, then in another. Turbor was gritting his teeth, while Munn blinked his eyes rapidly. It was as though they were keening their inadequate sensory equipment to locate this impulse which could not affect them.
Finally, Anthor shrugged and tossed the control box back into Darell’s lap. “Well, I suppose we can take your word for it. But it’s certainly hard to imagine that anything was happening when I turned the knob.”
“But naturally, Pelleas Anthor,” said Darell, with a tight smile. “The one I gave you was a dummy. You see I have another.” He tossed his jacket aside and seized a duplicate of the control box that Anthor had been investigating, which swung from his belt.
